能の安定保持も図るものである。SUMMARY OF THE INVENTION Accordingly, the present invention provides a fertilizer application method in which a distance sensor for detecting a distance between a fertilizer hopper and an upper surface of a fertilizer is mounted on the back of a hopper lid of a fertilizer hopper to adjust the amount of fertilizer fed in the fertilizer hopper. The amount control mechanism is driven and controlled based on the detection value of the distance sensor, and the amount of fertilization of the fertilizer is easily calculated based on the distance change based on the detection of the distance sensor, and the amount is required in the field during the fertilization operation. Maintains an appropriate amount of fertilizer at all times and grows crops such as rice well under substantially uniform field environment conditions to improve the productivity of crops. In addition, at the time of fertilizer replenishment work performed by opening the hopper lid, the distance sensor is not obstructed to this work, and the sensor performance is stably maintained.

可能とさせるものである。Further, a detection target member having a shape larger than that of the fertilizer and having a lower specific gravity is held on the upper surface of the fertilizer in the fertilizer hopper, and the distance to the target member is detected by a distance sensor.
Even when the amount of fertilizer stored in the hopper increases or decreases due to fertilizer application, fertilizer replenishment, or the like, the target member is always kept on the upper surface of the fertilizer, thereby enabling accurate detection of the fertilizer amount based on the detection of the distance sensor.

である。Further, a plurality of distance sensors are attached to the back surface of each hopper lid, the amount of fertilizer fed out of the hopper is calculated from the average value of the distance sensors for each line, and the fertilizer application adjustment mechanism is driven and controlled. Even when the amount of storage in all or each hopper and the upper surface of the fertilizer vary during the operation, the feed amount of all the lines is accurately calculated, and the adjustment of the fertilization amount can be made with high accuracy.
